GRATINGS

Hellma Cells is offering holographically and mechanically ruled
gratings from Carl Zeiss. Holographic styles include sinusoidal,
echelette and laminar types with wavelengths ranging from 4 nm to 1 µm.
These are suitable for spectrometers and monochromators for NIR to UV
and synchrotron radiation. Mechanical versions include sawtooth and
amplitude types with wavelengths from 4 nm to 25 µm. These gratings can
be used for spectrometers and monochromators for high-power lasers.
